If all that is so, it would suggest to me that it is possible that you have no refrigerant in the system and that the pressure switch is giving an incorrect reading (stuck, wiring fault etc.), which enables the compressor to keep cycling whilst empty.
When you were monitoring the pressure in Vida, did you see any major fluctuations as the compressor cycled? Can you read the return line and/or cooling coil temperature (I *think* I have seen this sensor data in VIDA for at least one Volvo I've owned but can't remember which model) to check the lines aren't cooling?
